Sobriety is pretty boring. Drugs enhance reality. At least my favorite ones do, like LSD. Of course they also distort it to an extent. MDMA is a nice social drug. Smoking weed is kind of shallow as far as the high goes, but it is a nice way to not be bored. Amphetamine can come in handy for studying. The novelty of trying new research chemicals is pretty cool. I like having religious experiences and can't really have them without psychedelics. I like to hack my brain. Even drugs like coke and heroin are fun to experiment with. I actually think heroin would be excellent to try if I get depressed, although that could be dangerous. When I tried heroin I felt orgasmic though and any cares or concerns I had were gone. I can see how that could be addictive though. Largely I would compare some drug use to playing video games though. It is entertaining, it is fun, it kills time, it feels good. Others are like I imagine church must be for some people, or going to therapy or a museum or a reading a good book. Spiritually cleansing, emotionally healing, aesthetically pleasing and intellectually stimulating. It really just depends on the specific drug. If I summed it up in two words for all drugs in general, it would have to be "reality enhancing" though, although the interpretation of that changes with the substance .
